Question

A light, inextensible cord passes over a light, frictionless pulley with a radius of 11 cm. It has a(n) 23 kg mass on the left and a(n) 4 kg mass on the right, both hanging freely. Initially their center of masses are a vertical distance 3.7 m apart.

The acceleration of gravity is 9.8 m/s2 .

At what rate are the two masses accelerat- ing when they pass each other?

Answer in units of m/s2.
